IMPROVEMENT IN BOILERS FOR STEAM-HEATERS.

Specification forming part of Letters Patent No. 134,044, dated December 17, 1872.

To all whom it 'may concer-n:

Be it known that I, PHILIP EsrEs, of Leavenworth, in the county of Leavenworth and State of Kansas, have invented a Vertical Boiler, of which the following is a specification:

The invention relates to a vertical boiler moreespeciallydesignedforheatinghot-houses or other buildings with hot water. It consists, first, in constructing the boiler and furnace proper in three easily-detachable sections,

A whereby the commonest mechanic can take it apart, cleanfand again put it together. It consists,'secondly, in providing the crownsheet with cups and circulatory tubes that hang down in the lire-chamber, to facilitate the heating operation.

In the drawing, Figure l is a vertical section through line x .1; of Fig. 2, and Fig. 2 is a top view with the dome removed.

Arepresents the boiler, cast in three sections-namely, the water chamber B, the crown-sheet C, and the dome D. These parts are bolted or fastened together so as to be readily separated. The water-chamberB surrounds the furnace-chamber D', has smokeues d and doors d leading thereinto, and has L two inner anges, b b', on top. The dome D is also provided with an outer ange on bottom, whereby it is easily bolted to the flange b of water and furnace chambers. The crownsheet C is also bolted to the other ange b', has two diagonal ribs, c c, on top, and has perforations c. To the under side of this crownsheet are attached cups E, which hang down in close proximity to the fire, and in them are loosely placed inner tubes-F, of sheet-iron,

forked at bottom. The purpose of this is to v secure a circulation and prevent the accumulation of sediment.

A boiler constructed in this manner has been practically tested by me at a pressure of two hundred and twenty-five pounds.

Having thus described my invention, what I claim as new,.and desire to secure by Letters Patent, is-

l. An upright heater having the water-chamber B, crown-sheet C, and dome D in separate and independent sections, constructed so as to be attached together in the manner described.

2. The crown-sheet C having cups E pendent in the lire-chamber and surrounding loose internal tubes F, as and for the purpose described.

PHILIP ESTES.
